if the length of a capillary tube is less than that required, will water come out of the capillary?

⭐The surface tension is an inter-facial force. The surface tension force pulls the liquid tangential to the wall of the capillary.
⭐When a capillary is dipped in water, it starts rising up due to pulling force from the solid-vapor interface. If the capillary has insufficient length, as the water rises it accelerates till the end of the capillary.
⭐ When it reaches the edge of the capillary, water would gain some kinetic energy and due to inertia it slightly overshoots the edge of the tube.
⭐ Then water surface bulges out due to which the tension at the solid-vapor interface turns downward which tries to pull the water column downward.
⭐The liquid column will make some oscillations and finally after sometime the oscillations dampen out due to viscous effects.
⭐At steady state, the water column will fill the entire capillary and the radius of curvature of the minuscus will be just about adjusted such that the vertical component of surface tension force would balance the weight of water column.
